Store 5 bikes. Be easily accessible for the kids without any lifting Be foldable to store away in the winter. Be low cost and very fast to build. I found this great Instructable and modified it for our use. It is different in that it is a foldable version, includes a plan, a parts list and a how to build video. The total cost was less than $40. if you have some of the parts already, it will cost less. The build time was about 1/2 an hour.

The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths — and address weaknesses — of the Internet’s current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. By naming data instead of their locations, NDN transforms data into a first-class entity. The current Internet secures the data container. NDN secures the contents, a design choice that decouples trust in data from trust in hosts, enabling several radically scalable communication mechanisms such as automatic caching to optimize bandwidth.
